Despite the significant health, social and economic costs of cigarette smoking, 17% of Ontarians still currently smoke. Use of smoking cessation pharmacotherapy such as Zyban (bupropion HCl) has been shown to double quit rates but such medications are under-utilized by smokers attempting to quit. It has been suggested that the high price of pharmacotherapy may act as a barrier to accessing such treatment.The main objective of this study is to evaluate the methods and effectiveness of providing smokers who want to quit with 8 weeks of free Zyban in combination with smoking cessation counselling through family health teams and community health centres across the province.
